Typically when most people say glass, this is what they’re thinking of. Window glass has to be durable enough to withstand extremes of weather and temperature but allow in light and permit exterior visibility. Window glass may be plain, beveled or etched for a bold accent look. Bevels and etching are usually fixtures of main entries like front and back doors. Beveled glass is cut on a slant around the sides, providing a gem-like appearance when viewed at an angle, while etched glass has a design burned into the glass. Frosted glass is essentially etched glass without a pattern, or with the pattern traced in clear glass during the etching process.
